“…However, fish also suppress large macroinvertebrate populations (Dorn 2008) including Odonata (Bendell & McNicol 1995;Feuchtmayr et al 2007;Henrickson 1988) and fish predation affects the size of macroinvertebrates (Blumenshine et al 2000). As fish populations become extinct, there is the potential for odonates to assume the role of top predator.…”

Climate change brings with it unprecedented rates of increase in environmental temperature, which will have major consequences for the earth's flora and fauna. The Odonata represent a taxon that has many strong links to this abiotic factor due to its tropical evolutionary history and adaptations to temperate climates. Temperature is known to affect odonate physiology including life-history traits such as developmental rate, phenology and seasonal regulation as well as immune function and the production of pigment for thermoregulation.

“…In the absence of Chaoborus larvae, the fact that 13 of 15 Leucorrhinia were preyed upon during the first 24 hours supports the lack of any predator avoidance behaviour in Leucorrhinia. Henrikson (1988) showed that Leucorrhinia suffers heavily from fish predation. Also in Coenagrion there was some predation by Aeshna.…”

The foraging behaviour of four coexisting odonate larvae; Coenagrion hastulatum (Charp.) Zygoptera, Aeshna juncea (L.) Anisoptera, Cord&a aenea (L.) Anisoptera and Leucorrhinia dubia (v d Lind.) Anisoptera was analysed under various conditions of prey type and abundance. Coenagrion and Aeshna used a sit and wait mode when the prey density was high and when the prey was evasive. When the prey abundance was low an active mode was used. In Aeshna an active mode was also used when prey was sedentary. Cordulia exhibited a sit and wait mode and Leucorrhinia an active mode under all prey treatments performed. The results indicate that a niche differentiation in foraging behaviour may be one of several ways to reduce food competition between these coexisting species. However a literature study on prey selectivity did not reveal any support for this suggestion. Interference from Aeshna altered the foraging behaviour of Coenagrion whereas that of Leucorrhinia remained unchanged. Further, Aeshna preyed heavily on Leucorrhinia and to a lesser extent on Coenagrion during interference trials. A field study did not show any negative correlation in abundance between Aeshna and Leucorrhinia or Coenagrion larvae. The results indicate interference competition may be more important than exploitation competition in the shaping of odonate larval communities.

“…Such a behavioral pattern was observed in Odonata species that inhabit water bodies without fishes in contraposition to those species that inhabit environments with fishes (McPeek, 1990a;McPeek, 1990b;Pierce, 1988;Pierce et al, 1985;Henrikson, 1988). Since aquatic vegetation represents a refuge against insectivorous fishes (Pierce, 1988;Gilinsky, 1984;Sazima and Zamprogno, 1985), it seems valid that predation upon Odonata is the principal selective pressure responsible for the differences in morphological patterns presented among the groups of species associated with different types of microhabitat.…”

“…In the region of the Middle Rio Doce, De Marco and Latini (1998) identified two groups of Anisoptera according to habitat type: i) species characteristics of areas with aquatic macrophytes and ii) species characteristics of the bottom substrate, found as much in areas with macrophytes as in areas without them. The presence of macrophytes provides conditions that affect the availability of prey and susceptibility to predation (Wellborn and Robinson, 1987;Dionne et al, 1990;Henrikson, 1988;Gilinsky, 1984). The architecture of this substrate separates the species that live preferably in macrophytes from those that live on the bottom substrate.…”

In the lakes of the Middle Rio Doce, Minas Gerais (MG), two groups of larval Libellulidae are distinguished by preferences of habitat use: one uses mainly aquatic macrophytes and the other uses the bottom substrate. The goal of this work was to verify if there is a morphological distinction between the two groups of species. Thirteen body measures were taken from the larvae and analyzed. No difference was found between the two groups of species regarding the body size, but shape differences were observed for two morphological variables. The species that use mainly macrophytes tend to have larger relative measures of the labium and smaller measures of the abdomen width. Advantages in resource obtainment and in vulnerability to predation are probably the explanations for the morphological divergence among these larval groups.Keywords: Ecomorphology, Libellulidae, macrophyte, Rio Doce. Ecomorfologia larval de 13 Libellulidae (Anisoptera, Odonata) do Vale do Médio Rio Doce, MG, Brasil ResumoNos lagos do Médio Rio Doce (MG), dois grupos de larvas de Libellulidae apresentam diferenças no uso do habitat: um utiliza preferencialmente macrófitas aquáticas e o outro utiliza a superfície do fundo. O objetivo deste trabalho foi verificar se existe uma distinção morfológica entre estes dois grupos. Treze medidas morfológicas foram tiradas das larvas e analisadas. Nenhuma diferença, com relação ao tamanho corporal, foi encontrada entre os dois grupos, embora diferenças de forma tenham sido observadas com relação a duas variáveis morfológicas. As espécies que usam principalmente macrófitas tendem a possuir maiores medidas relativas do lábio e menores medidas da largura do abdome, o oposto ocorrendo com as larvas habitantes do fundo. Vantagens na captura de presas e na vulnerabilidade à predação são provavelmente as explicações para a divergência morfológica observada entre os dois grupos de larvas.Palavras-chave: Ecomorfologia, Libellulidae, macrófitas, Rio Doce.
